All nations gate
West view of the All nations gate at Persepolis. This gate was not on Darius the great's initial plan for Persepolis but was added by his son and sucessor Xerxes. The initial main entrance of the palace complex was located on the south wall of the terrace supporting the palaces. Xerxes changed it, added a monumental stairway on the west side leading to that gate upstairs. The function of the gate was not only to allow the entry of the visitors, but was also to separate the people according to their social importance. The gate was a square hypostyle hall, with 3 doors. The few nobles and princes allowed to enter the royal palace were directed through the south door to a court opening on the Tachara (Darius's audience hall) or to the Tripylon palace, while the others were directed trough the east door on an alley leading to another gate (unfinished) and then the east barackments or the 100 column palace (said Xerxes's audience hall). The 4 columns are well preserved and supported a 18.5 meters high roof. The columns are ionian styllized, erected on inversed bell shapes, their top consisted in stylized palm trees. The walls were decorated with 2 giant bulls on the west, and 2 giant lamassus (androcephalic winged bulls) on the east protecting the path. The gate carry also a royal trilingual achaemenian cuneiform inscription by Xerxes known as XPa (see other pictures of the Ancient Iran set).
